VALVE-LOCK.

To all whom it may concern Be it known that I; GEORGE W; Cross, acitizen of the United States of America, and resident of Fort Smith, inthe county of Seof Arkansas, have in- Vented certain new and usefulImprovemerits in Valve Locks, of which the followadj ustinent' and '50 fnism engages a member ing' is a specification.

This invention relates to devices for protecting automobile n owners andusers against theft or unauthorized useof the autoinobile throughcontrol for the fuel line or the fuel supply, novel means being providedfor checking the flow of fuel and for retaining the checking meansagainst manipulation for unchecking the fuel line.

An object of this invention is to provide novel means for holding avalve in closed position or in different positions of adjustment inorder that a valve which may be utilized for controlling the flow offuel from a tank or source of supply to the motor may be so controlledasto interrupt the sup ly of fuel, novel means being provided forholding a portion of the valve against movement that the operator orowner of the automobile may look the parts in the position he desiresthem to remain.

A still further object of this invention is to provide a valve and avalve stem under the control of a retaining mechanism, means beingassociated with the mechanism for supporting the fuel line and forpreventing distortion or twisting of the said fuel line While the valveis mechanism being associated with means for retaining the valveoperating mechanism in different positions of adjustment and locked orimmovable. V

A. still further object of thieinvention is to provide a device of thecharacter indicated in which the lock or retaining mechawhich is capableof assuming different positions with relation to the locking mechanismin order that the valve may be moved a greater or less degree accordingto the requirements, the said arrangement permitting comparativelyminute affording lock engaging suraces While at the same time permittingthe comparatively minute adjustment.

A still further object of this invention is to provide, mechanism of thecharacter indicated having the advantages above stated associated with aprotecting casing for the Specification of Letters Patent. Applie'atiunfileflJuly 14, 1913.

valve stem and its operating mechanism and parts associated therewith. I

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describingthe invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, and in whichFigure 1 illustrates a sectional view of the controlling and retainingmechanism associated with a fragment of a fuel line, parts .of the saidmechanism being in elevation;

of a fuel line or supply pipe and 12 another section thereof with avalve 18 interposed for establishing communication be tween the twopipes. The valve 13 here shown is of the globe type, the same having avalve seat 14 for the valve 15, the said valve '15 having a valve stem16 with threads 17 by which .said'valve stem is caused to carry thevalve 15 toward or away from the owl'ng a'modified method of applying Inthese drawings 11 denotes one section seat, in order that the passage offuel through the said valve may'be controlled. The details ofconstruction of the valve casing are immaterial and will not. therefore.

be described more fully, as the foregoing will enable those skilled inthe art to understand the construction and operation of the valve, butthe valve illustrated in Fig. 1 has an internally threaded flange 18which is designed for engaging threads of a tubular housing 19 whichembraces the valve stem and other portions of the mechanism as willpresently appear.

The spindle 2O terminates in a socket 21, in which the valve stem 16 isseated, the said socket having a set screw 22 for binding against thevalve stem, so that the spindle 20 when turned will communicate motionto the valve stem in a rotary direction and cause the valve toreciprocate with relation to the valve seat. The outer end of thespindle may be provided with any appropriate hand grasp or handle, thesame being here shown as having a knob 23 and the said spindlefurthermore carries an indicator or pointer 24 in order that the degreeof movement or rotation of the spindle may be registered, and theoperator may know to what degree the valve has been moved. The spindleextends through the aperture 25, of a lock casing 26, the said lockcasing having a recess 27 for the reception of a plate 28, the

I edge of which has approximately square edges 29, the number of whichmay be varied to suit particular requirements. The plate here shown isapproximately square in plan, presenting four edges which may be broughtinto operative relation to the bolt 30 of the lock, the said bolt beinga part of a lock of any appropriate type, the lock here shown being ofthe barrel type and having a cylinder 32 to which a key 33 is fitted forthe purpose of operating the bolt, but as the interior .,construction ofthe lock is not a part of the present invention, it is not shown nor isit described in detail.

Associated with the casing 26 is an inner face plate 34 provided with anaperture 35 through which the spindle 20 projects and in which it isrotatable, the said plate 34 having an annular flange 36 which isinternally threaded for engaging the threads of the housing 19 and whenthe parts are in the assembled position shown in Fig. 1, the housingguards the Valve stem against access to or manipulation of the same. Asa means for preventing the turning, distortion or displacement of thefuel line when the valve is manipulated, a bracket 37 extends from theplate 34 and said bracket has a loop or eye 88 for receiving the fuelline and retaining it against displacement, as stated. The particularconstruction of the bracket may be varied, but is here shown ascomprising a one-piece metal structure which might be made by stampingthe same from sheet metal.

From an inspection of the drawing and from the foregoing description, itwill be obvious that the user of a controlling device forming thesubject matter of this invention may close the valve to prevent fuelfrom passing from the container, reservoir or tank to the motor of anaut0mobile,'and when the valve is seated, the lock'may be manipulated sothat the bolt thereof engages the plate 28, thereby preventing rotationof the said plate and consequently holding the spindle against rotationso that the valve cannot be opened until the mechanism is unlocked. Itis also obvious that by reason of the fact that the plate 28 has aplurality of edges a minute adjustment of the valve may be secured andthat the same may be locked in different positions of adjustment throughthe method heretofore explained.

In Fig. 8, I have illustrated the invention as applied to the floor ofan automobile body where the fuel pipe is extended horizontally whicharrangement is a very commonly adopted method of arranging the fuelline.

In Fig. 9, I have illustrated the invention as applied to a verticallydisposed fuel line 39 extending from the tank 40, the operatingmechanism, that is to say the handle 23 for operating the valve and thekey 38 of the lock projecting through the box of the front seat, thefuel tank being applied under the front seat. While I have referred'tothis invention as being used for a fuel line, it is obvious that itmaybe employed for a steamline, hot air line, or other fluid foroperating a motor or engine and I, therefore, do not wish to berestricted to the use of this invention. I

In the modification shown in Fig. 10, the fuel container or receptacle41 has a discharge pipe 42 which may lead to the motor or other place ofuse, and the said pipe 42 terminates in a nipple 43 which contains avalve casing 44, said valve casing being in communication with the pipe42 and having a valve plu 45 therein for controlling the passage of fuelfrom the interior of the re ceptacle or tank 41 to the pipe 42. Thereceptacle 41 may have any appropriate stuifing box 46, through whichthe valve stem 47 extends, said valve stem being connected to thespindle 20 through the medium of the socket '21 and set screw 22 whichhas heretofore been described.

I have shown in the drawings the. use of the invention as .associatedwith a globe valve and with a turning plug, therebyillustrating theinterchangeability and the divers uses to.which the invention may beput, and other uses may be suggested to those skilled in the art.

I claim- In a controlling mechanism for fuel lines, a valve casing, avalve therein, a fuel line connected to the valve casing, said valvecasing havin an annular flange internally threaded, a threaded valvestem connected to the valve and projecting from the casing, a housingthreaded on the annular (flange into which the valve stem projects,

l0 face plate having a lock case having a recess therein, a plate havingan angular edge rotatable in the recess, a spindle extending through thelock case, whereby the said valve is operated, a socket on the spindlefor receiving the end of the valve stem, means for holdingthe socket andvalve stem in assembled relation, a lock having a bolt adapted to engagethe said plate, a. face plate on the casing, said an annular flange toengage the end of the housing remote from the valve, and a bracketanchored on the said plate and having means for receiving and engagingthe fuel line.

In testimony whereof, I hereunto aflix my 15 signature in the presenceof two Witnesses.
